WHOOP Strap

1. Strain Tracking

• Strain measures the amount of physical effort your body undergoes. WHOOP calculates this based on heart rate data and your physical activity throughout the day.
• It offers a Strain Score, helping you understand how much work you’ve done and whether you’re pushing your body too hard.
• The goal is to help you optimize your training so you’re not over-training or under-training.

2. Recovery Tracking

• Recovery measures how well your body has recovered after intense physical activity.
• The app evaluates your HRV (Heart Rate Variability), resting heart rate, and sleep performance to calculate your Recovery Score (ranging from 0 to 100).
• A high recovery score means your body is well-rested and ready for more strain, while a low recovery score means your body needs rest.

3. Sleep Tracking

• The WHOOP Strap tracks your sleep stages: light sleep, deep sleep, and REM sleep.
• It provides detailed insights into how much time you spend in each stage and calculates a Sleep Performance Score.
• It also helps you optimize sleep duration and quality, which is essential for recovery.

4. Heart Rate Variability (HRV)

• WHOOP continuously measures your HRV, a key indicator of your autonomic nervous system and overall recovery.
• Higher HRV is typically linked to better recovery and reduced stress levels.

5. 24/7 Wearable

• WHOOP is designed to be worn around the clock, offering continuous monitoring of your body’s recovery and performance.
• It’s waterproof and has a long-lasting battery life (up to 5 days between charges).
